Ji'nan citizens drink high quality groundwater again
the reporter Xu Jia
the groundwater has finally entered the city, although it is not more than 20 thousand tons per day.
22 days early morning, the design of the water supply capacity of 100 thousand cubic meters of the daily water supply project began to water supply to the urban area. Considering the needs of the water supply, the water supply scale is controlled within 20 thousand cubic meters per day.
23 days, from the water source of cold Zhuang, to the Wang Zhuang bridge of Zhou, and then to the eight Li bridge area, the reporter of the water transporting artery visited dozens of miles into the city road of the groundwater in Jinxi.
a field visit to the water source of Jinxi water source -
water in the surrounding village is a famous
the Wang Zhuang bridge over the Zhou Dynasty. From the east to the west is the three water source of the city: the ancient city, the cold Zhuang, the bridge Lee. The underground water in Ji'nan is mainly from cold village and Qiao Zi Li.
23 days, the reporter came to the water source of one of the cold village, just come to the village to see a piece of corn, green trees become cloudy, but it is a good place for the beauty of water and water.
to the village, a water pipe with a diameter of about 10 centimeters is sprinkled with water. The water is cool. A lot of villagers who have just been busy from the ground wash the mud on their shoes, wash their faces and rest for a while.
the villagers said that the water of the pipe was drawn from the ground and used for watering the ground, but it could be drunk directly. The reporter took a taste of the bottle and had a sweet taste. The village's 42 year old coldest brother said, "there is a village in the village less than 2 miles away. The water there is not as good as our village. When our water is boiled, it is best to drink it when it is not cool, sweet and sweet, and the water in the Chuang is good. Everyone knows it. "
there are 5 water wells in this water source, on the edge of a piece of ground, surrounded by wire mesh, the staff said, more information is not easy to reveal.
22 days into the eight Li bridge water plant -
this call of water, only eight Li bridge water plant design capacity of 1/10
20 thousand cubic meters of groundwater into the home, relieving the urban water pressure, in fact, Jixi water is not the first "go to the city" rescue It's urgent. This winter, a small amount of water has been transferred to help Yuqing water plant ice.
in January 2010, Ji'nan continued low temperature. Because of the precipitation pool in the Yuqing water plant, the freezing phenomenon occurred in the cold weather. The thickest place reached more than 20 centimeters. If it continued to freeze, it would affect water production. "In winter, the temperature of the ground water is relatively high, which helps to turn the ice." At that time, the daily call of groundwater in 30 thousand cubic meters, thick ice in two days.
22 days into the eight Li bridge water plant, it was introduced that the water plant was built in 80s of last century, and has been used as a water treatment plant for groundwater treatment, with a design capacity of 200 thousand cubic meters per day. This time, considering the factors such as the conservation spring, the amount of the call of groundwater is strictly limited to 20 thousand cubic meters. Within the meter. It only takes 1/10 of the capacity of the Eight Mile Bridge waterworks.
water for the call to the main pipeline leading to the area without a movie mountain -
the water that was originally needed to save the south of the city to the north of the city,
because the water quality of the southern reservoir could not reach the water supply standard. At the beginning of the design and construction, the first phase of the emergency water transfer was to solve the southern city of Ji'nan. About 300 thousand of the residents in the area have a problem of draught.
but in the actual water diversion, it is found that the water of Yuqing water plant can reach the high terrain in the south of Ji'nan after the pressurization of Qixian pressure station and Jianshe Road pressure station. The problem of draught can be solved by the residents in the southern part of the city.
it is difficult for residents to use water because of the high terrain, and the pressure stations planned to be built are difficult for the land expropriation.
"20 thousand tons of water can only play a role in relieving the main pipeline." People in the industry say.
Jinxi underground water, zigzag road to city road -
crossing the river, crossing the railway, 3.6 km pipeline laid 57 days
at the end of 2009, the urban water supply in Ji'nan city was severely tested. The water supply of 3 mountain reservoirs in the south of wolves mountain, Jinxiu Sichuan and wolf Cat Mountain stopped water supply, and the southern part of the province was 300 thousand Residents are threatened with water. Under such circumstances, the Ji'nan municipal government approved the first phase of the Jixi emergency water diversion project in early 2010.
water diversion project west end of the Wang Zhuang bridge, Yuefu River, crossing the South Bank of the 220 National Road along the South Bank of the La mountain river, crossing the Beijing Shanghai route after the north bank, and finally along the mountain road north to the G220 national road through the ten West Road with the original underground water supply pipeline, which connects the original water source land and the ten West Road. Large arteries.
started in February 2nd and completed in March 31st, the 3.6 km pipeline was laid for 57 days. According to the engineering personnel involved in the construction, there are several difficulties: crossing jade river, crossing 220 National Road, crossing the wax mountain river, crossing the Beijing Shanghai railway, "the pipeline crossing the Yufu River and the La Shan River all cross the underground river, the water is large and the construction of the winter is very difficult; and the impact of crossing the 220 National Road is to be reduced to the lowest; Crossing railways is faced with problems such as coordination of procedures.
